## Job description

## About the Team

Codex is OpenAI’s first-party developer product focused on agentic software engineering. We’re building tools that help engineers design, write, test, and ship code faster—safely and at scale. We partner tightly with research and product to translate model advances into tangible developer productivity.

## About the Role

As a Data Scientist on Codex, you will measure and accelerate product-market fit for AI developer tools. You’ll define what “developer productivity” means for our product, run experiments on new coding models and UX, and pinpoint where the model helps or hurts across languages and tasks. Your insights will directly shape how an entire industry builds software. This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will

- Embed with the Codex product team to discover opportunities that improve developer outcomes and growth
- Design and interpret A/B tests and staged rollouts of new coding models and product features
- Define and operationalize metrics such as suggestion acceptance, edit distance, compile/test pass rates, task completion, latency, and session productivity
- Build dashboards and analyses that help the team self-serve answers to product questions (by language, framework, repo size, task type)
- Diagnose failure modes and partner with Research on targeted improvements (model quality signals, user feedback, evals)

You might thrive in this role if you have

- 5+ years in a quantitative role at a developer-facing or high-growth product
- Fluency in SQL and Python; comfort with experiment design and causal inference
- Experience defining product metrics tied to user value
- Ability to communicate clearly with PM, Eng, and Design—and to influence product direction

You could be an especially great fit if you have

- Strong programming background; ability to prototype, run simulations, and reason about code quality
- Familiarity with IDE/extension telemetry or developer tooling analytics
- Prior experience with NLP/LLMs, code models, or evaluations for generative coding

- **Founded**: 2015
- **Founders**: Sam Altman, Greg Brockman, Ilya Sutskever, John Schulman, Wojciech Zaremba, and others

## Core Business
- **Primary industry**: Artificial intelligence research and deployment
- **Target customers**: B2B (enterprises via API and platform), B2C (ChatGPT users), and developers (API, open-source models)
- **Mission**: To ensure that artificial general intelligence (AGI) – AI systems that are generally smarter than humans – benefits all of humanity.

## Products & Services
- **[ChatGPT](https://openai.com/chatgpt)**: Conversational AI assistant available via web and mobile, used by consumers and integrated into enterprise workflows.
- **[GPT-4 API](https://openai.com/product)**: Large language model accessed via API for developers to build AI-powered applications (text generation, summarization, code assistance, etc.).
- **[DALL-E](https://openai.com/dall-e-3)**: Image generation model that creates images from natural language descriptions.
- **[Whisper](https://openai.com/research/whisper)**: Open-source speech recognition system.
- **[OpenAI Agents](https://openai.com/)**: Emerging product category focused on autonomous AI agents that can perform tasks on behalf of users (announced June 2026).

## Market Standing
- **Valuation**: Not publicly disclosed in the provided sources. Widely reported in the press at ~$300 billion as of early 2026 (post-funding round), but this figure is not confirmed by OpenAI’s official materials.
- **Key Metric**: Total funding exceeds $13 billion from Microsoft and other investors. The company has also confidentially filed a draft S-1 with the SEC (see [openai.com](https://openai.com/) – “Confidential submission of draft S-1”).
- **Notable Investors/Partners**: Microsoft (strategic partner and largest investor), with additional participation from Thrive Capital, Sequoia Capital, Andreessen Horowitz, and others.
- **Growth Signals**: Active hiring with 721 open roles posted; expansion into agent-based products; confidential IPO filing; continued deployment of frontier models.

## Competitive Advantages
- **First-mover & brand recognition**: ChatGPT became the fastest-growing consumer app in history, establishing OpenAI as the household name in generative AI.
- **Research leadership**: Consistently publishes cutting-edge research (GPT-4, DALL-E 3, Whisper, etc.) and attracts top AI talent.
- **Compute & infrastructure**: Exclusive partnership with Microsoft provides massive cloud computing resources (Azure) for training and inference.
- **Unique governance structure**: The nonprofit parent ensures mission alignment (AGI benefiting humanity) while the for-profit arm can raise capital and scale products.

## Strategic Focus
- **Safe AGI development**: Continued emphasis on safety research, alignment, and responsible deployment (e.g., safety systems, model provenance).
- **Enterprise expansion**: Growing ChatGPT Enterprise and API offerings for businesses.
- **Agentic AI**: Building autonomous agents that can “transform work” (announced June 2026).
- **IPO preparation**: Confidential S-1 filing indicates intent to go public, which will require increased financial transparency and governance maturity.

## Why Work Here
